To all whom it may concern:

Be it known that I, WILLIAM L. DE RE- MER, a citizen of the UnitedStates, residing at Chicago, Cook county, Illinois, have inventedcertain new and useful Improvements in the Method of Rolling Tie-Plates,of which the following is a specification.

My invention relates to a new and useful method of rolling a tie platefrom a billet, slab, or other piece of metal into a con tinuous strip orbar which is sheared off in proper lengths to form a series of separatetie plates.

My new tie plate is particularly distinguished by the provision of ahook or overhanging flange on its upper surface which runs transverse ofthe plate (when out into lengths) or longitudinally. of the railandextends over or engages one side of the rail flange and results in manyadvantages in practice, among which may be named the following:providing for perfect contact between rail and plate and preventingsocalled shoulder mounting; entirely eliminating the cutting or neckingof the ad-- jacent spikes as there is no contact between such spikes andthe rail, and transferring the strain laterally to the hook which givesthe greatest area of resistance, having both horizontal and verticalopposition, etc., and my new method of rolling is particularly adaptedand designed for rolling such hook as a part of a continuous rollingoperation.

My new tie plate also by preference comprises in addition to said hook ashoulder on the upper face thereof transverse of the plate (when outinto lengths) or longitudinal of the rail for engaging the other side ofthe rail flange to prevent lateral movement of the rail and consequentcutting of the spikes, the spike holes being formed slightly inwardly ofthe said shoulder to engage the rail flange which, in case the spikesbecome worn at such point, is supported by the shoulder. This shoulderis advantageous for the additional reason that it minimizes spikecutting effect from longitudinal travel of the rail and oifers thegreatest resistance from reacting spring or so-cal'led back slap of therail ordinarily received by the inside spikes which offer feebleresistance especially on curvatures. My new method of rolling alsocontemplates the production of such shoulder as a part of the continuousrolling method or process as well as the production of flanges on theunder face of the tie plate extending transverse thereof when out intolengths.

While heretofore tie plates have been rolled from a billet or the like,yet under the methods heretofore practised it has been impossible tosatisfactorily roll a tie plate of the nature in question, particularlybecause of the presence of the hook or overhanging flange, for whichreason I have discovered and developed the new method of rolling abovereferred to in general and hereinafter described in detail.

In the drawings, Figures 1, 2 and 3 represent elevations of portions ofrolls showing in section the bar or strip in its different stages offormation, such figures when placed in order reading from right to leftrepresenting the rolling machinery as far as the finishing rolls; Fig. 4an elevation of the finishing rolls illustrating in section the finishedbar or strip; Fig. 5 a cross section on the irregular line 55 showingone of the tie plates sheared from the bar or strip and the lowerportion of a rail in place thereon; Fig. 6 a plan view of such tie plateof. the form for use with ordinary spikes; Fig. 7 a cross section(similar to Fig. 5) showing a form of tie plate with which screw spikesare used; and Figs. 8 and 9 views similar to Figs. 5 and 6 butillustrating a plate with the transverse shoulder omitted.

Before explaining my new method of rolling, I will describe the tieplate itself, particularly its characteristic feature.

As shown in Figs. 5 to 9, the completed tie plate, which is of coursemade of metal, preferably steel, consists of the flat plate or bodyportion 1 having on its upper surface a hook or overhanging flange 2extending transversely thereof, or in a direction longitudinal of therail. This hook is adapted and designed to cooperate with or overhangone side of the rail flange 3 as clearly indicated in Fig. 5,'therebyholding the rail securely in place and resisting both hori- Zontal andvertical strains or pressures, insuring particularly a perfect contactbe tween rail and plate. By preference, the hook is thickened somewhatat its neck portion as indicated at 2? in Fig. 5, or at least maderather thick thereat in order to give the hook great strength at suchpoint and thereby enable it to resist vertical pressures especially incase the spikes on the other end of the tie plate should becomeloosened.

A tie plate as thus far described is illus trated in Figs. 8 and 9, butI prefer, however, to provide it with additional features. Describingsuch preferred form of tie plate, I provide the same on its uppersurface with a shoulder 4 extending transversely thereof and parallelwith the hook 2, as shown in Figs. 5, 6 and 7. This shoulder is adaptedto engage the other side of the rail flange and prevent lateral movementof the rail and thereby resist rail pressures in this direction as wellas rail travel, with the result that the spikes are protected againstcutting and are relieved from back slap of the rail which is taken bythe shoulder. This shoulder 4 presents preferably a straight Verticalface to the rail flange and sufficient clearance is provided between thehook and the rail and also between the rail and the shoulder to permitof the insertion and re moval of the plate without disturbing the rail.In practice a clearance of about of an inch is provided between the railand the shoulder in respect to a rail flange hav ing a width of say 5%inches, but the exact dimensions and clearance are immaterial so long asit is possible to properly apply and remove the tie plate withoutdisturbing the rail. The said hook and shoulder are so designed as toinsure ease of application of the plate to the tie without disturbingthe rail or impairing the efficiency of the plate.

The tie Plate is provided on one end with one or more spike holes 5 andon the other end with similar holes 6, the latter extending inwardlyslightly beyond the vertical side of the shoulder 4 in order that thespikes may press against the adjacent side of the rail flange and takeup any clearance that may exist between the rail flange and theshoulder. Such arrangement of spikes and spike holes is used as a methodof adjustment for rolling mill variations as allowed in the rolling ofrails. As herein shown and by preference, the tie plate is provided onits under side with transverse flanges 7.

Having now described the tie plate, I will explain the method of rollingthe strip or bar from which the tie plates are out, beginning with thebillet, slab or other piece of metal employed, and following the samethrough the different passes of the rolls to the completion thereof as afinished strip or bar, ready to be out up into tie plate widths, itbeing understood that in the present explanation of the rolling method Iwill describe the rolling of the strip from which the tie plate in itspreferred complete form as shown in Figs. and 6 is cut. In the presentinstance and by preference I use in the rolling process, as far as thefinishing rolls, what is called a three-high mill, meaning thereby top,middle and bottom rolls herein designated in general by the referencecharacters A, B and C respectively, although if desired a so-calledtwohigh mill might be employed but with more handling of the strip orbar. As to the finishing rolls, I employ a two-high mill comprising thetwo rolls D and E.

Referring to the preferred practice of my method by the apparatus hereinshown, which is illustrated in the usual diagrammatic way, the usualbillet (ir piece of metal is reduced by pass No. 1 to the formillustrated at the right-hand end of Fig. 1, whereby somewhat similarbut reversed recesses 8 have been formed on opposite sides of the billetby means of the middle roll 13 and bottom roll C. At this time there isthus formed from one side of the billet a rudimentary hook 9. Afterpassing through pass No. 2, the rudimentary hook becomes slightlyfurther developed and the body (indicated at 10) of the plate isparticularly developed from the right-hand side of the billet by meansof the top and middle rolls A and B respectively, as clearly indicatedin Fig. 1, but the portions of such plate are still angular. At the sametime the lower left-hand corner 11 of the billet is assuming the form ofa plate. By means of the next pass, No. 3, at which the middle andbottom rolls are active, the hook 9 is still further developed, becomingelongated and attenuated and likewise the downwardly projecting portion11 of the plate becomes still further developed. Moreover, the angularportions 10 constituting the main body of the plate assume a more nearlyhorizontal position. At the next pass, No.

4, at which the top and middle rolls are active, the main body of theplate is brought to a horizontal position with the hook 9 extendingsubstantially vertical and with the projecting portion 11 on the lowerside of the plate extended laterally or outwardly, as clearly indicatedin Fig. 2. At the next pass, No. 5, the upper surface of the plate isrolled with the shoulder 12 and two similar swells 13 by means of themiddle and bottom rolls, such swells being immediately above the twosimilar partially formed flanges or ribs 14.- on the under face of theplate. At this time the hook 9 and projection 11 are slightly changed inform and relation to each other, as clearly shown by an inspection ofFig. 2. At the next pass, N0. 6, at which the top and middle rolls areactive, the hook 9 becomes somewhat more pronounced and the projection11 is beginning to be turned toward the horizontal. At the next pass,No. 7, the hook 9 is in a substan'tially vertical position and theprojection 11 is approaching a horizontal position which is almostattained in pass No. 8. In this latter pass the hook 9 is itself turned'of the body of the bar.

over slightly inwardly and toward the body of the plate and the ribs 14:become more completely formed, the material of the swells 13 beingemployed for the purpose of the more complete formation of said ribs.The strip or bar is now ready to be presented to the finishing rolls inpass No. 9, wherein the hook is rolled to final form by the top andbottom rolls D and E, shown in Fig. at, so as to constitute practicallya flange adapted to overhang the'fiange of a rail, the projection 11having been brought to a horizontal position to serve as a partSimultaneously with this rolling of the hook inward and toward theplate, the flanges or ribs are finished by rolling down said swells.Moreover, at the same time and in pass No. 9, the shoulder 12 is finallyformed or finished by reducing the thickness of metal at the right handside of the blank (see pass No. 8) which metal in being reduced to thefinal thickness of the finished plate, as shown in pass No. 9, is causedto flow to completely finish said shoulder.

The result of the method or process of rolling above described is,broadly speaking, a long bar or strip which is cut into proper lengthsto form the separate tie plates as seen in Fig. 6, such bar or striphaving on its upper face a continuous hook or overhanging flange 2,which by preference is also provided with the shoulder 4.

The particular tie plate described is adapted to be secured to the tieby means of the ordinary form of spikes 16, but if the screw spike suchas shown at 17 in Fig. 7 is em ployed, the tie plate is slightlymodified as to its end portions in order to conform to the contour ofthe under side of the head 17 of such screw spikes. In other respectsthe structure of the tie plate is the same.

hile I have described my plate as a tie plate, used in the ordinarymanner of such devices, yet it will be understood that owing to thepeculiar structure thereof the same may also be utilized as a railjoint, particularly when the rails are light in weight.
